In all honesty, taking the time to write out a long and meaningful log isn't as easy if the cache location isn't interesting. If the Geocaching adventure is a good one, then a long and meaningful log is of course to be expected. I don't put a simple "Long hike, good hiding spot. TFTC" on a cache with a significant D/T rating, because to me, it is an insult to the CO's efforts in setting up an amazing cache.
Again, the geocaching process is also related to the cache, so I understand when people do put the time and effort to transcribe their words and experiences into the log for the CO.
Each to their own liking, but I was always taught by my community that a good Found It log is essential to keeping some CO's motivated, as it signifies people actually enjoy their caches enough to put it into words.
